UDP

write()

Writes UDP data to the buffer - no data is actually sent. Must be wrapped between beginPacket() and endPacket(). beginPacket() initializes the packet of data, it is not sent until endPacket() is called.

// PROTOTYPES
virtual size_t write(uint8_t byte);
virtual size_t write(const uint8_t* buffer, size_t size);

// SYNTAX
Udp.write(message);
Udp.write(buffer, size);

Parameters:

• message: the outgoing message (char)
• buffer: an array to send as a series of bytes (byte or char)
• size: the length of the buffer

Returns:

• byte: returns the number of characters sent. This does not have to be read
